Answer:
28.26
Step-by-step explanation:
the equation for circumference is 2pi*r or pi*d
3.14*9 (the diametre) is 28.26
Answer 28.26
1st rectangle:
width: 2.48cm
length: 4.96
2nd rectangle:
width: 4.96 (equals to the length of the 1st rectangle)
area: 9.92
length: 9.92/4.96 = 2
Since a stop sign is an octagon it has eight sides. So the perimeter will be:
p=8x, p=perimeter and x=side length. We are told that the perimeter is equal to:
16x^2-80x so we can say:
16x^2-80x=8x subtract 8x from both sides
16x^2-88x=0 factor out 8x
8x(2x-11), since we know x>0
x=11/2
x=5.5 units
Step-by-step explanation:
recommended is to convert to decimal
1/5 is 0.2
1/2 is 0.5
1/3 is 0.33
Order is 1/5, 1/3, 1/2
12 eggs = $3
8 eggs = (8÷12) × $3
